healthy gay man

Intermittent fasting has received much attention among health experts recently as a viable way to lose weight. Instead of following extreme diets, followers of this regimen restrict their food intake at certain times while eating normally at other times to lose weight.

As a weight-loss technique, intermittent fasting has been around for ages, but it started to gain attention in 2012 thanks to a BBC documentary by Dr. Michael Mosley called “Eat Fast, Live Longer” and the book “The Fast Diet.” Subsequent books increased the interest in intermittent fasting.

Although many people think of fasting as a somewhat painful religious ritual where one foregoes food for extended amounts of time, intermittent fasting is different, with many medical experts indicating that it is a viable weight-loss method. Harvard University Health notes that intermittent fasting not only makes intuitive sense but that it also seems to work with the human body’s circadian rhythms.

To that end, the world of technology has joined the intermittent fasting bandwagon with the creation of apps that make losing weight just a little bit easier. We have gathered and analyzed the best apps for intermittent fasting on the market. The main points used to evaluate these apps were: basic features, premium or add-on features, user experience and user interface. Finally, we have also included a short description of to whom the app is targeted for each review.
